If you have an HTC Incredible, you probably noticed that as of the 2.2 update Verizon saw fit to include an agonizing popup every time you plug your phone in, telling you to install vCast Media Manager. Here's how to disable that. I use this phone as my main test device, so I get to see that thing dozens of times a day. No more!
Here's how to disable it:
* Go to the dialer, dial ##7764726
* Hit Call
* Type Password 000000 (six zeros)
* Select Feature Settings -> CD ROM
* Disable it
